Nocturnal periodic breathing of chronic opioid users has been predominantly documented by the use of polysomnography. No previous studies have assessed the opioid effects of respiratory rhythms throughout the day without the use of physical restraint. We recently developed a contact-free unconstraint vital sign monitoring system with four load cells placed under the bed legs, which allows continuous measurements of respiratory change at the center of gravity on the bed. We aimed to reveal details of the patient's 24-h respiratory status under a monitoring system and to test the hypothesis that respiratory rhythm abnormalities are opioid dose-dependent and worsen during the night time. Continuous 48-h respiratory measurements were successfully performed in 51 patients with advanced cancer (12 opioid-free patients and 39 opioid-receiving patients). Medians of respiratory variables with minimal body movement artifacts were calculated for each 8-h split time period. Compared with opioid-free patients, opioid-receeasurements of respiratory changes of center of gravity on the bed, this study is the first to assess detailed respiratory characteristics throughout day and night periods without interference of daily activities in patients with advanced cancer receiving opioids. Respiratory rhythm irregularity is a predominant specific feature of opioid dose-dependent respiratory depression particularly in female patients with advanced cancer.While it has long been known that contraction robustly stimulates skeletal muscle glucose uptake, the molecular steps regulating this increase remain incompletely defined. The mammalian ortholog of Sir2, sirtuin 1 (SIRT1), is an NAD+-dependent protein deacetylase that is thought to link perturbations in energy flux associated with exercise to subsequent cellular adaptations. Nevertheless, its role in contraction-stimulated glucose uptake has not been described. The objective of this study was to determine the importance of SIRT1 to contraction-stimulated glucose uptake in mouse skeletal muscle. Using a radioactive 2-deoxyglucose uptake (2DOGU) approach, we measured ex vivo glucose uptake in unstimulated (rested) and electrically stimulated (100 Hz contraction every 15 s for 10 min; contracted) extensor digitorum longus (EDL) and soleus from ?15-wk-old male and female mice with muscle-specific knockout of SIRT1 deacetylase activity and their wild-type littermates. Skeletal muscle force decreased over the contrer in female compared with the male skeletal muscle. To our knowledge, this is the first demonstration of sex-based differences in contraction-stimulated glucose uptake in skeletal muscle.Diminished cerebrovascular function is associated with reduced cognitive ability. Habitual exercise may maintain or improve cerebrovascular function; however, limited information exists regarding the optimal exercise prescription for cerebrovascular health. Although aerobic exercise is associated with improved systemic vascular function, the influence of resistance exercise on vascular health is unclear. Therefore, the purpose of this study was to examine the influence of habitual exercise training on cerebrovascular function in healthy young adults. We evaluated 13 untrained (age?=?27?±?5?yr; 11 men, 2 women), 13 aerobic-trained (age?=?28?±?5?yr; 10 men, 3 women), and 13 resistance-trained (age?=?24?±?4?yr; 11 men, 2 women) adults. Middle cerebral artery velocity (MCAv), mean arterial pressure (MAP), and end-tidal carbon dioxide were continuously measured at rest and in response to hypercapnia. https://www.selleckchem.com/products/mm3122.html At rest, there were no differences between groups for MCAv, however, resistance-trained adults had greater cerebrov and untrained individuals. Despite this finding, the mode of habitual exercise training had a moderate influence on resting cerebral hemodynamics such that resistance-trained adults had greater cerebrovascular conductance compared with aerobic-trained adults.The inability to assess and measure changes to the airway smooth muscle (ASM) in vivo is a major challenge to evaluating asthma and its clinical outcomes. Bronchial thermoplasty (BT) is a therapy for asthma that aims to reduce the severity of excessive bronchoconstriction by ablating ASM. Although multiple long-term clinical studies of BT have produced encouraging results, the outcomes of BT treatment in practice have been variable, and questions remain regarding the selection of patients. Previously, we have demonstrated an imaging platform called orientation-resolved optical coherence tomography that can assess ASM endoscopically using an imaging catheter compatible with bronchoscopy. In this work, we present results obtained from a longitudinal BT study performed using a canine model (n = 8) and with the goal of investigating the use of orientation-resolved optical coherence tomography (OR-OCT) for measuring the effects of BT on ASM. We demonstrate that we are capable of accurately assessing ASM both beforrtant role in asthma treatments targeting ASM.There are more than 6,000 known rare diseases (RDs), which are often serious, chronic, and progressive conditions. Cumulatively, having a RD is actually common, impacting an estimated 300 million people worldwide. While the stigmatization of some specific RDs has been studied, examining stigma in a large sample of many RDs allows for a broader understanding of patterns.
We used inductive qualitative content analysis to analyze survey responses to an open-ended question about challenges of living with a RD among 384 people with 178 distinct RDs.
We identified eight codes which were organized under the following three themes structurally enacted, interpersonally enacted, and felt stigma. People with RDs experience structurally enacted stigma in the forms of healthcare stigma, education/workplace stigma, and an overall lack of accessibility. They also face interpersonally enacted stigma, including insufficient social support, a lack of understanding from others, and capitalist norms of productivity and self-sufficiency. Additionally, they experience felt stigma related to shame and the pressure to pass as able-bodied.
Possible solutions to RD stigma include increased education about RDs for healthcare professionals, a societal shift towards prioritizing accessibility, strengthened legal protections for disabled people, and expanded disability justice-focused community organizing.
